fix: disable log reporter in plugin tests for stable validation

Plugin tests validate trace segments only. The log reporter sends
werkzeug/framework log data to the mock collector, which causes
/dataValidate to fail when expected.data.yml doesn't include log items.

Disable log reporting in the base docker-compose config so all
plugin tests only produce segment data for validation.
